Two tales of forbidden love intertwine in this dark fantasy romance. A stoic heiress set to inherit her mother's business finds herself falling for a slave who is forging a rebellion against her. Meanwhile, a mad queen decides to marry a slave-turned-prince even though he plans to kill her. Both unlikely pairs must choose between love and duty. Are they willing to give up everything they hold dear to protect each other, or will they end up slitting each other's throats? A hundred years ago, the gods granted Clostrum and its surrounding countries elemental stones of power, but only women could use them. This turned Clostrum into a matriarchal society reliant on slaves to mine these stones. Evelyn Payne is the heir to a family whose mines and weapons have protected the country for years. After her twentieth birthday, her mother sends her to one of these mines in disguise to learn responsibility and root out corruption among the employed guards within. Once her work there is done, she will inherit the mine. However, as she gets to know the male slaves who toil away underground and the women who oversee them, her beliefs and loyalties are swayed by a kind-hearted slave who makes her wish she could become more than a pampered noble or tyrannical leader. As Evelyn fights her feelings toward Francis and tries to maintain order in the mine, she realizes his wish to escape his chains may endanger both his life and her position. If she doesn't prevent him from fueling the flames of rebellion, her mother will. Fans of Defy the Night, Spinning Silver, and Mistborn will adore this tragic tale of love and loyalty.
